Improvements of the programmable quantum current generator for better traceability of electrical current measurements
Sophie Djordjevic, Ralf Behr, Dietmar Drung +2
A programmable quantum current generator based on the application of Ohm's law to quantum voltage and resistance standards has demonstrated a realization of the ampere from the ele…
Inter-laboratory nanoamp current comparison with sub-part-per-million uncertainty
Stephen Giblin, Dietmar Drung, Martin Goetz +1
An ultrastable low-noise current amplifier (ULCA) has been transferred between two laboratories, NPL and PTB, four times, with three of the transfers yielding a relative change in…
Electrometer calibration with sub-part-per-million uncertainty
Hansjörg Scherer, Dietmar Drung, Christian Krause +2
We performed calibrations of four different commercial picoammeters using the Ultrastable Low-noise Current Amplifier (ULCA) as a calibrator current source operated in the range be…
